Project Config Cache is not updating Xcode version

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 7.0.8

Describe the bug
When running ns run ios --log trace the Project info that is displayed doesn't reflect the same info from ns doctor.

This is the relevant piece from ns run ios --log trace. If you compare the Xcode version shown here it doesn't match the Xcode version when I run ns doctor.

I'm not sure how to clear the cache that's being picked up on ns run ios but I'm having issues with the command line starting the app on my phone with iOS 14. I can start it fine from Xcode but it won't start from ns run ios and I think it might be related to ns run ios using an old Xcode version.

首先使用 ns run ios --log trace 和 ns doctor 重现这一差异，重点关注 Project Config Service 的缓存信息以及报告的 Xcode 版本。跟踪 ns run ios 期间如何读取缓存，并将其与 ns doctor 返回的最新值进行比较；完成的标准是两个命令都报告当前的 Xcode 版本。
